ASTM D897 Tensile Strength Test Equipment for Metal to Metal Adhesive Bonds

Adhesion failure refers to the lack of adhering to metals being fastened. It should be stated whether this temperature is that of the bond line, or of the atmosphere at which the assembly is to be maintained. This will be based on a visual inspection. Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements. Last previous edition D — However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.

Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive. Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive.

Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.

This standard is subject to revision at d87 time by the responsible technical committee and must be reviewed every? NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the adhesive itself. ASTM D e1. Use the self-aligning type. Have a question about conducting the test for this standard?

G Mechanical Wedge Grip. Do this by grinding the adhesive-faced surface? ASTM D is primarily comparative.

Originally published as D — Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal.

However, it does have application as a discriminator in determining variations in adherend surface sstm parameters and adhesive environmental durability. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D It is preferable to grind all metal specimens at the same time.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The grips shall be attached to the?

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such asfm, are entirely their own responsibility. Current edition approved Oct. In order to ensure that complete information is available to the individual conducting the tests, the manufacturer of the adhesive shall furnish numerical values and other speci?

Start test loading of the specimen as quickly as possible.

That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. We are confident that we have what you are looking for.

Test a substitute specimen to replace the discarded result. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable d97 space Affordable testing option for tension, compression, bend, peel and much more.

A range may be prescribed for any variable by the manufacturer of the adhesive if it can be assumed by the test operator that any arbitrarily chosen value within astj a range or any combination of such values for several variables will be acceptable to both the manufacturer and the purchaser of the adhesive.

By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0.
